Ideal Heating is a Hull-based manufacturer and one of the UK's largest boiler brands by volume. The Logic Max is their flagship combi, targeting the mid-to-premium market.
Efficiency
The Logic Max achieves up to 94% ErP efficiency — solid A-rated performance. Not quite at the very top of the efficiency tables, but the practical difference versus a 95% boiler amounts to a few pounds per year.
Output range
Available in 24, 30, and 35 kW outputs. The Logic Max Heat is the system boiler equivalent. Covers most residential applications.
Warranty
10 years with registration — competitive with the rest of the field at this price point. Ideal's warranty terms are straightforward, requiring annual service by a Gas Safe engineer.
Reliability
The Logic Max has an excellent reliability record in our experience. Ideal's UK parts availability is excellent — one of the fastest parts turnarounds of any UK brand, which matters if something does need replacing.
Controls
OpenTherm compatible. Works well with Hive, Nest, and Tado. Ideal also offer their own iMega thermostat, which is straightforward to use.
Price
The Logic Max typically sits below Worcester Bosch Greenstar 8000 and Vaillant ecoTEC Plus pricing, making it good value relative to warranty and performance.
Verdict
A reliable workhorse with a solid warranty and excellent UK parts support. A particularly good choice for budget-conscious homeowners who don't want to compromise significantly on quality.
